【発明の属する技術分野】
本発明は、真空掃除機に関し、より詳しくは、排気フィルタを掃除機本体に対し支持する排気フィルタカバーを、掃除機本体に堅固に取り付けることができるようにする排気フィルタカバーの締付装置に関する。
【０００２】
【従来の技術】
図４に示すように、一般の真空掃除機の本体２の一側には、空気が排気される排気部４が設けられている。前記排気部は、真空掃除機の本体の内部に流入される塵芥を含む空気から塵芥が除去された空気を掃除機の外部に排出させるものである。
この排気部４は、図５に示すように、上部ケーシング６と下部ケーシング８からなる掃除機の本体ケーシングの一側面に設けられた排気孔６ａに、フィルタ４ｂ及び排気フィルタカバー４ａを取り付けることにより形成されている。
【０００３】
前記排気フィルタカバー４ａは、その外側の突起４ｃが、排気孔６ａが設けられた本体ケーシングの外側部分の取付溝に挿入されることにより固定されている。
また、前記フィルタ４ｂは、排気空気中に含まれている塵芥を最終的に濾過させるものである。前記フィルタ４ｂは、前記排気フィルタカバー４ａと前記排気孔６ａとの間に介在し、前記排気フィルタカバー４ａが本体に取り付けられることにより、その間で保持されている。
【０００４】
このような従来の構造によると、前記排気フィルタカバーが掃除機本体の側面に直接取り付けられていることが分かる。掃除機本体は、掃除のために移動するが、例えば、この移動中に壁等にぶつかると、前記排気フィルタカバーが離脱するおそれがあった。しかも、前記排気フィルタカバーが掃除機本体に結合される部分でも、根本的に堅固な支持構造を提供することができなかった。
上述した従来の技術によると、真空掃除機の本体ケーシングに結合される排気フィルタカバーは、堅固な支持構造を提供しなかったという問題があった。
【０００５】
【発明が解決しようとする課題】
本発明は、上記問題点に鑑みなされたものであり、排気フィルタカバーを真空掃除機の本体の外側面に堅固に支持するように構成される締付装置を提供することを目的とする。
【０００６】
【課題を解決するための手段】
上記の目的を達成するために、本発明による真空掃除機の排気フィルタカバーの締付装置は、複数個の排気孔を有し、内側にフィルタを支持している排気フィルタカバーの内側端部に、内周縁側に突設された係止突起を形成し、真空掃除機の本体ケーシングの内部に固定されるモータハウジングの側面に設けられる円形の排気部の円周から側面に突設された排気フランジ部の外側面に、前記係止突起が係合される締付溝を設けて、前記排気フィルタカバーを固定することを特徴とする。
【０００７】
また、他の実施の形態による締付装置は、複数個の排気孔を有し、内側にフィルタを支持している排気フィルタカバーの内側端部に、放射状の外側に突設された係止突起を形成し、真空掃除機の本体ケーシングの内部に固定されるモータハウジングの側面に設けられる円形の排気部の円周から側面に突設された排気フランジ部の内側面に、前記係止突起が係合される締付溝を設けて、前記排気フィルタカバーを固定することを特徴とする。
【０００８】
また、前記締付溝は、外側から内側に直線方向に設けられた挿入部と、該挿入部に直角な排気フランジ部の円周方向に設けられた係合部とを備えている。
また、前記係合部の入口部分に係止段を設けて、係合された突起の締付状態をより堅固に維持している。
【０００９】
【発明の実施の形態】
以下、本発明の好ましい実施の形態を、添付図面に基づいて詳しく説明する。図１に示すように、本発明による排気フィルタカバー１０は、外側面に複数個の通気孔を有する円筒状になっている。また、前記排気フィルタカバー１０の円周面１１には、内部に突設された係止突起１４が複数個設けられている。また、排気フィルタカバー１０の内側には、排気される空気から塵埃を浄化するためのフィルタ１２が設けられている。
【００１０】
このような本発明の排気フィルタカバー１０は、真空掃除機の本体に組み込まれているモータハウジング２０に取り付けられる。本発明によると、排気フィルタカバー１０を真空掃除機のケーシングの内部に固定されているモータハウジング２０に締め付けることにより、従来のものに比べ、より堅固な支持構造を提供することができ、さらに、前記モータハウジング２０から排気される空気が、排気フィルタカバー１０に円滑に排気されるようになる。
【００１１】
前記モータハウジング２０の側面には、モータハウジングの内部を経由した空気が排気される排気部２２が設けられ、前記排気部２２は、排気フランジ部２４の内側に設けられている。前記排気フランジ部２４は、円形の排気部２２の円周部分から外側に一定の長さを有して突設されている。
また、前記排気フランジ部２４の外側部分には、前記係止突起１４が弾性的に係合される締付溝２６が設けられている。前記締付溝２６は、前記係止突起１４が弾性的に結合され支持されるものであれば、いずれの構成のものも適用することができる。
【００１２】
図示の第１の実施の形態では、前記締付溝２６は、外側から直線方向に挿入可能に凹設された挿入部２６ａと、前記挿入部２６ａから円周方向に直角をなすように形成された係合部２６ｂとからなる。即ち、前記締付溝２６は略Ｌ字状に設けられ、前記係止突起１４が、一度挿入後、回転により完全に係合された状態になるようにし、締付状態をより堅固に維持するように構成されている。
【００１３】
本発明による排気フィルタカバー１０を締め付けるためには、前記係止突起１４は、前記締付溝２６に挿入されるとき、先ず、前記挿入部２６ａに挿入された後、排気フィルタカバー１０を一定に回転させると、前記係合部２６ｂの端部まで係止突起１４が結合され、完全に係合された状態を維持することができる。図２は、このように完全に結合された状態を示す断面図である。図２の符号Ｃは、真空掃除機の本体のケーシングである。
【００１４】
また、図示のように、前記係合部２６ｂに係止突起１４が完全に挿入されると、合成樹脂材の弾性力により任意に離脱することが防止される。この任意に離脱することをさらに防止するために、前記係合部２６ｂの入口部分に凸状に突出した係止段２６ｃを形成することも好ましい。
以上のような第１の実施の形態では、前記排気フィルタカバー１０の内側部に内側に向かって突設された係止突起１４を形成し、これに対応するモータハウジング２０の排気フランジ部２４の外周縁部に凹状に締付溝２６を形成し、両者が結合するように構成されている。
【００１５】
次に、図３に示す本発明の第２の実施の形態について説明する。図示のように、この実施の形態では、前記排気フィルタカバー３０の円周面４１の内側端部には、外側に突出した係止突起３４が設けられている。また、モータハウジング４０の排気部４２の排気フランジ部４４には、その内周縁部に締付溝４６が設けられている。この実施の形態においても、前記係止突起３４が締付溝４６に弾性的に係合されることにより、排気フィルタカバー３０がモータハウジング４０に弾性的に係合される。
【００１６】
この実施の形態においても、前記締付溝４６は、上述した第１の実施の形態の締付溝と同一の形状に構成することができるのは勿論である。
本発明によると、フィルタ１２が内部に取り付けられている排気フィルタカバー１０を、モータハウジング２０の排気部２２に締め付けて固定することを基本的な技術的思想としている。
このような本発明の基本的な技術的思想を逸脱しない範囲内で、当業界の通常の知識を有する者にとっては、他の多くの変更が可能であろう。また、本発明は、添付の特許請求の範囲に基づいて解釈されるべきであることは言うまでもない。
【００１７】
【発明の効果】
上述した本発明によると、内部にフィルタが組み込まれている排気フィルタカバーをモータハウジングに直接締め付けるように構成することにより、排気フィルタカバーをより堅固に支持することができる効果がある。また、前記締付溝をＬ字状に形成すると、排気フィルタカバーがより堅固に締め付けられて支持される効果を有する。
